Tuna Mayo Onigiri (ツナマヨおにぎり, Tsuna Mayo Onigiri)

Tuna mayo sounds almost too ordinary to deserve ceremony. Good. Onigiri is everyday food, and everyday food is where a cuisine shows whether it knows what it's doing. Here the filling is canned tuna, Japanese mayonnaise, and one small drop of soy sauce. Nothing grand. Nothing hidden.

The one detail that decides it is the rice. Shape it while it's warm, not hot enough to burn your hands and not cold enough to turn stiff. Warm rice clings to itself without being crushed, and it lets the salt on your palms season the outside cleanly. Press too hard and you make a brick. Press too timidly and the center wanders out like it has an appointment elsewhere.

We make onigiri by touch, not by force. Wet your hands so the rice doesn't stick, salt them because the outside should taste alive, then cup the rice around the tuna mayo and shape it in three or four gentle presses. The nori goes on at the end if you want it crisp, or around the rice early if you're packing it and like it soft. Both ways are honest. The rice just has to hold, and the filling has to stay quietly in the middle.
